Abstract
New business insights are shown to be extractable from patent landscapes by the mathematical method of discrete Pareto analysis. By applying to patent publication distributions, a method analogous to that proposed by the linguist George Kingsley Zipf, metrics and methods of visualization are introduced which quantify scale, dominance and consolidation of a patent landscape. The key results of the method are illustrated in the Zipf plot of assignee patent publication count versus assignee rank for the lithography patent landscape shown below.
